(a)                                  If the Closing occurs after December 31, 2005, then the Cash Purchase Price payable by the Buyer on the Closing Date shall be increased by an amount equal to the interest on $370 million from January 1, 2006 to (but not including) the Closing Date at a rate of 6.0% per annum.

(b)                                 Prior to the Closing (but no less than two Business Days prior to the Closing Date), the Seller shall deliver to the Buyer (i) the consolidated balance sheet of the Company and the Retained Subsidiaries as of December 31, 2005 or (ii) if the balance sheet described in clause (i) is not available, the then most recent regularly prepared month end consolidated balance sheet of the Company and the Retained Subsidiaries (which shall be as of a  date not more than 50 days prior to the Closing Date).  The balance sheet delivered pursuant to the foregoing sentence is referred to as the “Month End Balance Sheet” and the date of such Month End Balance Sheet is referred to as the “Month End.”  The Month End Balance Sheet shall be accompanied by a schedule setting forth an estimate of the Adjusted Net Working Capital as of the close of business on the Month End (the “Estimated Adjusted Net Working Capital”).  The Month End Balance Sheet shall be prepared in accordance with GAAP (except for the exclusion of the Transferred Subsidiaries), applied on a basis consistent with (except for the exclusion of the Transferred Subsidiaries), and following the accounting principles, procedures, policies and methods employed in preparing, the unaudited consolidated balance sheet of the Company and its Subsidiaries as of August 31, 2005 (the “August 31 Balance Sheet”).  If the Estimated Adjusted Net Working Capital set forth on the schedule accompanying the Month End Balance Sheet is less than $26 million, the Cash Purchase Price payable to the Seller at the Closing shall be reduced by an amount equal to such deficiency.  If the Estimated Adjusted Net Working Capital set forth on the schedule accompanying the Month End Balance Sheet exceeds $26 million, the Cash Purchase Price payable to the Seller at the Closing shall be increased by an amount equal to such surplus.

SECTION 3.2.  Post-Closing Determination.  Within 60 calendar days after the Closing Date, the Seller shall deliver to the Buyer the consolidated balance sheet of the Company and the Retained Subsidiaries as of the close of business on the Measurement Date (the “Closing Balance Sheet”).  The Closing Balance Sheet shall be prepared in accordance with GAAP (except for the exclusion of the Transferred Subsidiaries), applied on a basis consistent with (except for the exclusion of the Transferred Subsidiaries), and following the accounting principles, procedures, policies and methods employed in preparing, the August 31 Balance Sheet.  The Closing Balance Sheet shall be accompanied by a schedule setting forth the actual Adjusted Net Working Capital as of the close of business on the Measurement Date (the “Actual Adjusted Net Working Capital”).  During the preparation of the Closing Balance Sheet by the Seller and the period of any dispute with respect to the application of this Section 3.2, the Buyer shall cooperate with the Seller to the extent reasonably requested by the Seller to prepare the Closing Balance Sheet and the Actual Adjusted Net Working Capital Report or to investigate the basis for any dispute.  The calculation of the Actual Adjusted Net Working Capital shall be examined by the Buyer who shall, not later than 30 calendar days after receipt of the Closing Balance Sheet, deliver a report thereon (the “Actual Adjusted Net Working Capital Report”) to the Seller.  The Actual Adjusted Net Working Capital Report shall list those items included in the Actual Adjusted Net Working Capital, if any, to which the Buyer takes exception and the Buyer’s proposed adjustment.  If the Buyer fails to deliver to the Seller the Actual Adjusted Net Working Capital Report within 30 calendar days following receipt of the Closing Balance Sheet, the Buyer shall be deemed to have accepted the Actual Adjusted Net Working Capital for the purposes of any adjustment to the Purchase Price under Section 3.3.  If the Seller does not give the Buyer notice of its objections to the Actual Adjusted Net Working Capital Report within 30 calendar days following receipt of the Actual Adjusted Net Working Capital Report, the Seller shall be deemed to have accepted the Closing Balance Sheet as adjusted by the Buyer in the Actual Adjusted Net Working Capital Report for the purposes of any adjustment to the Purchase Price under Section 3.3.  If the Seller gives the Buyer notice of its objections to the Actual Adjusted Net Working Capital Report, and if the Seller and the Buyer are unable, within 15 calendar days after receipt by the Buyer of the notice from the Seller of objections, to resolve the disputed exceptions, such disputed exceptions will be referred to Deloitte & Touche LLP or another firm of independent certified public accountants (the “Independent Accounting Firm”) mutually acceptable to the Seller and the Buyer.  The Independent Accounting Firm shall, within 60 days following its selection, deliver to the Seller and the Buyer a written report determining such disputed exceptions, and its determinations will be conclusive and binding upon the parties thereto for the purposes of any adjustment to the Purchase Price under Section 3.3.  The fees and disbursements of the Independent Accounting Firm acting under this Section 3.2 shall be apportioned between the Buyer and the Seller based on the total dollar value of disputed exceptions resolved in favor of each such party, with each such party bearing such percentage of the fees and disbursements of the Independent Accounting Firm as the aggregate disputed exceptions resolved against that party bears to the total dollar value of all disputed exceptions considered by the Independent Accounting Firm.  For the avoidance of doubt, the delivery and timing of receipt of any document sent by the parties pursuant to this Section 3 shall be governed by the provisions set forth in Section 13.5 — “Notices.”

SECTION 3.3.  Post-Closing Adjustment.

(a)                                  If the Actual Adjusted Net Working Capital is less than the Estimated Adjusted Net Working Capital, the Seller shall, within three calendar days following the final determination of the Actual Adjusted Net Working Capital pursuant to Section 3.2, and based upon such final determination, pay to the Buyer the amount of such deficiency in cash, together with interest on such amount from and including the Closing Date to but excluding the date of payment at a rate of 6.0% per annum.  Any payment by the Seller to the Buyer under this Section 3.3(a) shall be made by wire transfer of immediately available funds to such account as the Buyer shall designate in writing to the Seller.

(b)                                 If the Actual Adjusted Net Working Capital is more than the Estimated Adjusted Net Working Capital, the Buyer shall, within three calendar days following the final determination of the Actual Adjusted Net Working Capital pursuant to Section 3.2, and based upon such final determination, pay to the Seller the amount of such excess in cash, together with interest on such amount from and including the Closing Date to but excluding the date of payment at a rate of 6.0% per annum.  Any payment by the Buyer to the Seller under this Section 3.3(b) shall be made by wire transfer of immediately available funds to such account as the Seller shall designate in writing to the Buyer.

41

relate to the Company and its Retained Subsidiaries and to the extent reasonably necessary to evaluate the purchase of the Membership Units) of the Company and its Subsidiaries and, during such period, shall furnish promptly to the Buyer and Level 3 all other information concerning the Company and the Retained Subsidiaries, properties and personnel as the Buyer and Level 3 may reasonably request to evaluate the transactions contemplated hereby; provided that neither Leucadia nor the Seller shall be required to provide access to any such properties, personnel or information to the extent relating exclusively to the Excluded Assets or Excluded Liabilities.  Leucadia and the Seller also shall cause each of the Company and the Retained Subsidiaries to afford to the Buyer and Level 3 reasonable access to its assets and operations throughout the period prior to the Closing Date to evaluate the transactions contemplated hereby.  Unless otherwise agreed to by Leucadia and the Seller, all information provided to Buyer and Level 3 and their advisors and representatives shall be kept confidential in accordance with the terms of the Confidentiality Agreement; provided, however, that such obligation will terminate upon the Closing with respect to information relating to the Company and the Retained Subsidiaries (except, if the Buyer has not exercised the Benefit Plan Substitution Right pursuant to Section 2.2(b), in connection with Level 3’s and the Buyer’s investigation of the Transferred Benefit Plans in accordance with Section 7.16).  No investigation or receipt of information pursuant to this Section 7.3 shall qualify any representation or warranty of Leucadia or the Seller or the conditions to the obligations of the Buyer or Level 3.

SECTION 7.4.  Pre-Closing Transfers.  On or prior to the Closing, Leucadia and the Seller shall cause the Company and the Retained Subsidiaries to transfer to one or more entities directly or indirectly wholly owned by Leucadia (other than the Company or the Retained Subsidiaries) (the “Transferee”) all of the right, title and interest of the Company and the Retained Subsidiaries in and to the Excluded Assets.  Such transfer shall be on an “as is, where is” basis, and the Company and the Retained Subsidiaries will make no representations or warranties, either express or implied, to the Transferee with respect to the Excluded Assets and the Transferee will have no recourse against the Company and the Retained Subsidiaries with respect to the Excluded Assets or the Excluded Liabilities.  In addition, Leucadia and the Seller shall cause the Transferee to assume and to pay, perform, settle and discharge when due all obligations with respect to the Excluded Liabilities.  Furthermore, to the extent that any of the Excluded Assets or the Excluded Liabilities require the Company and the Retained Subsidiaries to perform obligations thereunder (including any guarantees), Leucadia and the Seller shall, prior to the Closing, obtain from the other parties thereto the written unconditional release of the Company and the Retained Subsidiaries from all obligations (including any guarantees) and liabilities under such contracts and provide any required notices to any Person or shall otherwise indemnify the Buyer and Level 3 with respect thereto without limitation pursuant to the provisions of Section 9.3(b)(ii) and (iii) hereof.  In connection with obtaining the release of the Company and the Retained Subsidiaries from the Company’s Credit Documents, the Company may borrow funds from Leucadia or an Affiliate of Leucadia and, subject to Section 7.15(a), such inter-company loans will be repaid by the Company at or prior to the Closing.  For purposes of this Agreement, such transfer of the Excluded Assets and assumption of the Excluded Liabilities and release or indemnification of the Company’s and the Retained Subsidiaries’ obligations thereunder (including any guarantees) are collectively referred to as the “Pre-Closing Transfers.”  Notwithstanding the foregoing, prior to transferring the capital stock, membership units or other ownership interests of the Transferred Subsidiaries to the Transferee, Leucadia and the Seller shall cause the Company and the Retained Subsidiaries to transfer to the Company or a

42

(c)                                  The parties agree that a monetary remedy for a breach of the agreements set forth in Sections 7.11(a) and (b) hereof will be inadequate and impracticable and further agree that such a breach would cause Level 3 and the Buyer irreparable harm, and that Level 3 and the Buyer shall be entitled to temporary and permanent injunctive relief without the necessity of proving actual damages.  In the event of such a breach, Leucadia and the Seller agree that Level 3 and the Buyer shall be entitled to such injunctive relief, including temporary restraining orders, preliminary injunctions and permanent injunctions as a court of competent jurisdiction shall determine.

SECTION 7.13.  Tax Matters.

(a)                                  All transfer, documentary, sales, use, stamp, registration and other such Taxes, and all recording charges (including any penalties and interest) incurred in connection with consummation of the transactions contemplated by this Agreement shall be paid by the Buyer and the parties shall cooperate in the filing of all necessary Tax Returns and other documentation with respect to such Taxes and charges.

(b)                                 (i) The Seller shall prepare and file, or cause to be prepared and filed, when due all Tax Returns that are required to be filed by or with respect to the Company and its Subsidiaries for all Pre-Closing Tax Periods to the extent that such Tax Returns are required to be filed on or prior to the Closing Date, taking into account all valid extensions of time to file such returns. The Seller shall also prepare and file or cause to be prepared and filed when due all

46

Tax Returns that are required to be filed by or with respect to the Company and its Subsidiaries for all Pre-Closing Tax Periods to the extent such Tax Returns relate to Income Taxes, irrespective of when due.  (ii) The Buyer shall prepare and file or cause to be prepared and filed when due all Tax Returns that are required to be filed by or with respect to the Company and its Subsidiaries for all Pre-Closing Tax Periods to the extent that such Tax Returns relate to Taxes other than Income Taxes and are required to be filed after the Closing Date, taking into account all valid extensions of time to file such returns.  (iii) The Seller shall pay, or cause to be paid, any Taxes due in respect of any such Tax Returns in excess of any Taxes reflected in the determination of the Actual Adjusted Net Working Capital, which shall be paid by the Company, but such limitation shall have no application to Income Taxes.  In the case of Tax Returns prepared by the Buyer pursuant to clause (ii), the Buyer shall cooperate with and shall follow the direction of the Seller in the preparation of such Tax Returns and the Seller shall pay over to the Buyer the amount of any Tax owing under such Tax Return to be paid by the Seller under this Section 7.13(b) within three days of receiving notice from the Buyer of such amount, which notice shall be delivered not be less than seven days prior to the due date of such return; provided, however, that there is at least substantial authority for the positions required to be taken on such Tax Returns.  The Tax Returns prepared pursuant to the first sentence of clause (i) and clause (ii) shall be prepared consistent with past practice unless there shall be no reasonable basis therefor and unless the failure to prepare such returns in such a manner would not reasonably be expected to have a material and adverse effect on the Company, the Retained Subsidiaries or the Buyer after the Closing.

(c)                                  The Buyer shall prepare and file, or cause to be prepared and filed, when due all Straddle Tax Returns and shall cause the Company to pay the Taxes shown to be due thereon; provided, however, that the Seller shall pay over to the Buyer within three days of receiving notice from the Buyer of such amount, which notice shall be delivered not less than seven days prior to the due date of such Straddle Tax Return for the portion of any such Tax that relates to the portion of the Straddle Period ending on the Closing Date, but only to the extent in excess of any Taxes reflected in the determination of the Actual Adjusted Net Working Capital, which shall be paid by the Company.  The Seller will furnish to the Buyer all information and records reasonably requested by the Buyer for use in preparation of any Straddle Tax Return.  The Buyer shall furnish the Seller with a completed draft of any Straddle Tax Return for the Seller to review and comment upon no later that 20 days before the Buyer files any such return or such shorter period that may be practical in the circumstances, provided that reasonably adequate time under the circumstances is provided to the Seller for such review.  The Buyer shall not file any such Straddle Tax Return without the Seller’s consent, which consent may not be unreasonably withheld, conditioned or delayed.

(d)                                 In the case of any Straddle Period, (i) Property Taxes of the Company and its Subsidiaries for the Pre-Closing Tax Period shall be equal to the amount of such Property Taxes for the entire Straddle Period multiplied by a fraction, the numerator of which is the number of days during the Straddle Period that are in the Pre-Closing Tax Period and the denominator of which is the number of days in the Straddle Period; and (ii) the Taxes of the Company and its Subsidiaries (other than Property Taxes) for the portion of the Straddle Period that constitutes a Pre-Closing Tax Period shall be computed as if such taxable period ended as of the close of business on the Closing Date.  If necessary because the assets were reported to the tax authorities on a combined basis (i.e., Closing occurs on or before December 31, 2005), the

47

Property Taxes shall be allocated by the Buyer between the assets acquired in this transaction and the Buyer’s remaining assets in accordance with the Buyer’s reasonable asset allocation practice.  If the Buyer’s allocation is disputed by the Seller, then the Seller and the Buyer shall negotiate in good faith to resolve such dispute.

(e)                                  If a Tax authority commences any audit, examination, litigation or otherwise makes any claim or proposes any adjustment that relates to a Pre-Closing Tax Period (other than an Straddle Period) (collectively, a “Tax Proceeding”), then the Buyer shall promptly furnish written notice to the Seller of such Tax Proceeding.  Failure to give such notice shall not relieve the Seller from any liability which it may have on account of this indemnification or otherwise, except to the extent that the Seller is prejudiced thereby.  The Seller shall have the shorter of (i) 45 days after receipt of such notice or (ii) 15 days less than the number of days before a response to the relevant Tax authority is required, but in no event shall the Seller have less than 15 days, to decide whether to undertake, conduct and control (through counsel of its own choosing and at its own expense) the response to such Tax Proceeding and the settlement or defense thereof, and the Buyer shall fully cooperate with Seller in connection therewith including, but not limited to, providing powers of attorney authorizing Leucadia (or its designee) to control and take action in connection with any such Taxes.  The Seller shall permit the Buyer to participate in such response, settlement or defense through counsel chosen by the Buyer (but the fees and expenses of such counsel shall be paid by Buyer).  If any settlement materially adversely affects any Subsidiary in a Post-Closing Tax Period, the Seller shall not pay or settle any such claim without the prior written consent of Buyer (which consent shall not be unreasonably withheld, conditioned or delayed).  If within the shorter of (x) 45 days after the receipt of the Buyer’s notice of a Tax Proceeding or (y) 20 days less than the number of days before a response to the relevant Tax authority is required (but in no event less than 20 days), the Seller does not notify the Buyer that the Seller elects (at its cost and expense) to undertake the defense thereof, or gives such notice and thereafter fails to contest such claim in good faith, then the Buyer shall have the right to contest, settle or compromise such Tax Proceeding and the Buyer shall not thereby waive any right to indemnity for such Tax Proceeding under this Agreement and, for the avoidance of doubt, the Buyer shall be indemnified by the Seller for the Buyer’s reasonable costs, including attorneys’ and consultants’ fees in defending and settling such proceedings; provided, however, the Buyer shall not, and shall cause the Subsidiaries not to, pay or settle any such Tax Proceedings without the prior written consent of Seller (which consent shall not be unreasonably withheld, conditioned or delayed).

(f)                                    If a Tax authority commences any audit, examination, litigation, or otherwise makes any claim or proposes any adjustment that relates to a Straddle Period (collectively, a “Straddle Period Tax Proceeding”), then the Buyer shall promptly furnish written notice to the Seller of such Straddle Period Tax Proceeding.  Failure to give such notice shall not relieve the Seller from any liability which it may have on account of this indemnification or otherwise, except to the extent that the Seller is prejudiced thereby.  The Buyer shall undertake, conduct and control (through counsel of its own choosing and at its own expense) the response to such Straddle Period Tax Proceeding and the settlement or defense thereof.  The Seller shall cooperate with the Buyer in connection therewith, and the Buyer shall permit the Seller to participate in such response, settlement or defense through counsel chosen by the Seller (but the fees and expenses of such counsel shall be paid by Seller). To the extent any settlement adversely affects the Seller in a Pre-Closing Tax Period, the Buyer shall not pay or settle any

48

such claim without the prior written consent of the Seller (which consent shall not be unreasonably withheld, conditioned or delayed).  If within the shorter of (i) 45 days after the receipt of the Buyer’s notice of a Straddle Period Tax Proceeding or (ii) 15 days less than the number of days before a response to the relevant Tax authority is required (but in no event less than 15 days), the Buyer fails to contest such claim in good faith or to prevent action to foreclose a lien against or attachment of the Buyer’s property, then the Seller shall have the right to contest, settle or compromise such Straddle Period Tax Proceeding and the Seller shall not thereby waive any right to indemnity for such Straddle Period Tax Proceeding under this Agreement; provided, however, the Seller shall not pay or settle any such Straddle Period Tax Proceeding without the prior written consent of the Buyer (which consent shall not be unreasonably withheld, conditioned or delayed).

(g)                                 The Buyer shall not, and shall not permit any of its Affiliates to, carry back any loss, credit or other Tax attribute of the Company or any of its Subsidiaries to a Pre-Closing Tax Period without the prior written consent of the Seller, which consent may not be unreasonably withheld, conditioned or delayed.

(h)                                 All tax sharing, indemnity or allocation agreements or arrangements among the Company and its Subsidiaries on the one hand and Seller, Leucadia or their Affiliates on the other hand shall terminate at or prior to the Closing and the parties thereto shall have no further obligation thereunder.

(i)                                     ▇▇▇▇▇ ▇ and the Buyer, on the one hand, and Leucadia and the Seller, on the other hand, will cooperate with each other in connection with the preparation and filing of Tax Returns required under this Agreement and will provide to each other access, at any reasonable time and from time to time, at the business location at which the books and records are maintained, after the Closing Date, to such Tax data relating to the Company and the Retained Subsidiaries as Leucadia and the Seller or ▇▇▇▇▇ ▇ and the Buyer, as the case may be, may from time to time reasonably request.

SECTION 7.14.  Name.  Promptly after the Closing, Leucadia and the Seller shall cause WilTel Aircraft Leasing, LLC, a Delaware limited liability company, and WilTel Technology Center, LLC, a Delaware limited liability company, to change their names to such names that do not include “WilTel” and to otherwise cease using such name in its operations.

SECTION 7.15.  Reimbursements; Cash Balance.

(a)                                  If the Closing occurs after December 31, 2005, the Seller shall pay to the Company at the Closing an amount equal to all cash used by the Company, the Retained Subsidiaries or the Business on and after January 1, 2006 with respect to Excluded Liabilities (including, without limitation, (i) payments of interest or principal under the Company’s Credit Documents or the Company’s Real Estate Debt Documents and (ii) payments of operating and maintenance expenses or capital expenditures with respect to the Company’s Tulsa, Oklahoma headquarters) or Excluded Assets (including, without limitation, payments to acquire marketable securities).

49

(b)                                 If on the Measurement Date, the Company and the Retained Subsidiaries have an aggregate cash balance of less than $100 million (after giving effect to the Pre-Closing Transfers), the Seller shall make a contribution to the capital of the Company on the Measurement Date to the extent necessary to cause the Company and the Retained Subsidiaries to have a $100 million aggregate cash balance immediately following the Measurement Date.

(c)                                  The Seller shall on the Closing deliver to the Buyer a certificate signed by an officer of the Seller setting forth in detail all of the amounts to be reimbursed pursuant to Section 7.15(a).

(vi)                              (A) the Retirement Plan and all other pension plans maintained or sponsored by or to which contributions are required of any ERISA Affiliate and that are subject to Title IV of ERISA or Section 412 of the Code, including, but not limited to (1)

53

claims of the PBGC, the IRS and any other Governmental Agency relating to the funding of such plans, (2) claims of participants and beneficiaries relating to benefit payments under such plans and (3) claims relating to fiduciary violations under ERISA, and (B) the Deferred Compensation Plan; provided, however, that if the Buyer exercises its Benefit Plan Substitution Right in accordance with Section 2.2(b), neither Leucadia nor the Seller shall have any liability with respect to the Retirement Plan or the Deferred Compensation Plan hereunder;

(ii)                                  the maximum amount for which Leucadia and the Seller shall be liable with respect to matters covered by Section 9.2(a)(i) (other than with respect to (x) Section 5.6, (y) Section 5.10 (limited however to Income Taxes) and (z) the second and third sentences of Section 5.23(c)) or Section 9.2(a)(iv) shall not exceed in the aggregate $100 million;

In

54

the case of any Tax benefits realized after the indemnity amount has been paid by the Seller (but within the five-year period following the Closing Date), the Buyer shall make a further payment to the Seller when such benefits are received.  Tax benefits shall be considered realized when there is a reduction in the Buyer’s liability for Taxes, determined by comparing the amount of such liability without the Tax benefits to the amount of such liability when such Tax benefits are taken into account;

(vii)                           the parties agree that, if the liabilities pursuant to Section 9.2 exceed $50 million in the aggregate, Leucadia and the Seller shall be entitled to satisfy 50% of such liabilities in excess of $50 million by delivery of Shares, with stock powers duly endorsed, with the value of each Share at the time of such payment being deemed to be the average of the volume weighted sales prices per share of Level 3 Common Stock as reported by the NASDAQ Stock Market (or such other nationally recognized trading market on which the Level 3 Common Stock is then principally traded) for the 10 trading-day period ending upon the trading day immediately preceding the date that Leucadia and/or the Seller makes the payment pursuant to this Section 9.2;

SECTION 9.3.  Indemnification by Level 3 and the Buyer.

(a)                                  Notwithstanding the Closing and regardless of any investigation at any time made by or on behalf of the Seller or Leucadia or of any knowledge or information that the Seller or Leucadia may have, the Buyer and Level 3 shall jointly and severally indemnify and fully defend, save and hold Leucadia and the Seller harmless if Leucadia or the Seller shall at any time or from time to time suffer any Losses arising out of or resulting from, or shall pay or become obligated to pay any sum on account of any one or more of the following:

(i)                                     any breach of any representation or warranty of Level 3 or the Buyer contained in this Agreement or in any certificate delivered to Leucadia or the Seller in connection with the Closing;

(ii)                                  the maximum amount for which the Buyer and the Seller shall be liable with respect to matters covered by Section 9.3(a)(i) (other than with respect to Section 6.6) shall not exceed in the aggregate $100 million;

(iii)                               in all cases determining whether there has been a breach of a representation or warranty by the Buyer or ▇▇▇▇▇ ▇ for purposes of this Section 9.3, or in determining the amount of any Losses with respect to such breach, such representations and warranties shall be read without regard to any materiality qualifier contained therein;

(iv)                              the parties agree that any amount payable to the Seller or Leucadia made pursuant to this Section 9.3 shall be treated for tax purposes as an adjustment to the Purchase Price, unless otherwise required by applicable law;

(v)                                 the parties agree that any amount payable to the Seller or Leucadia made pursuant to this Section 9.3 shall be calculated net of any tax benefits realized in cash (or as an offset to an obligation payable currently) within a period of five years following the Closing Date by the Indemnitee or its Affiliates as a result of the Loss.  In the case of any Tax benefits realized after the indemnity amount has been paid by the Buyer (but within the five-year period following the Closing Date), the Seller promptly shall make a further payment to the Buyer when such benefits are received.  Tax benefits shall be considered realized when there is a reduction in the Seller’s liability for Taxes, determined by comparing the amount of such liability without the Tax benefits to the amount of such liability when such Tax benefits are taken into account; and

(vi)                              if the Buyer exercises the Benefit Plan Substitution Right, the Buyer and Level 3 shall indemnify Leucadia and the Seller for any Losses arising out of or resulting from, or shall pay or become obligated to pay any sum on account of, the Retirement Plan and the Deferred Compensation Plan.

SECTION 9.4.  Procedures for Indemnification.  Other than as set forth in Section 7.13(e) and (f), if a party entitled to indemnification under this Section 9 (an “Indemnitee”) asserts that a party obligated to indemnify it under this Section 9 (an “Indemnitor”) has become obligated to such Indemnitee pursuant to Section 9.2 or 9.3, or if any suit, action, investigation, claim or proceeding is begun, made or instituted as a result of which the Indemnitor may become obligated to an Indemnitee hereunder, such Indemnitee shall give written notice to the Indemnitor; provided, however, that the failure of the Indemnitee to give prompt notice to the Indemnitor shall not release the Indemnitor of its indemnification obligations hereunder, except to the extent the Indemnitor shall have been materially prejudiced by such failure.  The Indemnitor agrees to defend, contest or otherwise protect the Indemnitee against any such suit,

56

action, investigation, claim or proceeding at its sole cost and expense subject to the provisions of this Section 9.  The Indemnitor shall have the sole power to direct and control the defense of any such suit, action, investigation, claim or proceeding.  The Indemnitee shall have the right, but not the obligation, to participate at its own expense in the defense thereof by counsel of the Indemnitee’s choice.  The Indemnitee shall make available all information and assistance that the Indemnitor may reasonably request and shall fully cooperate with the Indemnitor in such defense, including with respect to indemnification with respect to Taxes, providing powers of attorney authorizing Leucadia or its designee to control and take action in connection with any such Taxes.  In the event of a failure of the Indemnitee to provide cooperation as required under this Section 9.4, the Indemnitor’s obligation to indemnify the Indemnitee shall be reduced to the extent of the Losses with respect to which the Indemnitor’s ability to defend against the action, investigation, claim or proceeding underlying such indemnification obligation has been prejudiced by such failure.  The Indemnitor shall not compromise or settle any such suit, action, investigation, claim or proceeding unless (x) such compromise or settlement is on exclusively monetary terms and shall be paid entirely by the Indemnitor (subject to the provisions of Section 9.2(b)(i) and (ii) and 9.3(b)(i) and (ii), which shall be controlling) and the Indemnitee receives an unconditional release in such compromise or settlement or (y) the Indemnitee shall have consented in writing to the terms of such compromise or  settlement, which consent shall not unreasonably withheld; provided, however, that if the Indemnitee fails to consent thereto, the Indemnitor’s liability with respect to such matter shall not exceed the proposed settlement amount.  If the Indemnitor fails timely to defend, contest or otherwise protect against such suit, action, investigation, claim or proceeding, the Indemnitee shall have the right to do so, including, without limitation, the right to make any compromise or settlement thereof, and the Indemnitee shall be entitled to recover the entire cost thereof from the Indemnitor subject to the provisions of this Section 9, including, without limitation, reasonable attorneys’ fees, disbursements and amounts paid as the result of such suit, action, investigation, claim or proceeding.

SECTION 9.5.  Exclusive Remedy.  From and after the Closing Date, the sole and exclusive remedy for any breach or failure to be true and correct, or alleged breach or failure to be true and correct, of any representation or warranty or any covenant or agreement in this Agreement, except for claims relating to fraud or for injunctive relief, shall be indemnification in accordance with this Section 9.
